Frequently Asked Questions

How much can insulation and duct sealing save on energy bills?+

Proper insulation and sealed ducts can reduce heating/cooling costs by 15-30%. For Sacramento homes, that's typically $200-$500 per year in savings, plus improved comfort.

What is R-30 insulation?+

R-30 is the minimum insulation level recommended for Sacramento attics. R-value measures resistance to heat flow — higher is better. Many older Sacramento homes have R-11 or less, meaning they're losing significant energy through the attic.

Can I stack these with a heat pump rebate?+

Yes! Insulation ($1,000) + duct sealing ($800) + heat pump HVAC ($3,000) = up to $4,800 in total rebates. Improving insulation and ducts also makes your new heat pump more effective.
